4 Claims. (01. it- 13 2) My invention relates to improvementsin advvertising apparatus for use particularly in window Z display advertisingalthough, aswill presently appear, it may be otherwise used if desired.

' {5 The principal object of the invention is to provide a strikingvari-colored advertising display of the illuminated type: having asparkling backi ground and which is inexpensive to manufacture, installandoperate. Other objects of a more or less subordinate nature, are alsocomprehended by my invention, i all of which together with the precisecharacter of my improvements will be readily apparent when g thesucceeding description andclaims are read [5 5 I with reference to theaccompanying drawings.

Insaid drawings:- I Figure 1 is a view in front elevation of a preferredembodiment of my invention,

jFigure 2 is a 'view in top plan,

Figure 3 is a view in vertical transverse section taken on the line 3-3of Figure 1 looking in the direction indicated by thearrows, and Figure4 is a fragmentary view in horizontal section, partly broken away; takenon the line 44 of Figure 3 looking downwardly and drawn to an enlargedscale. Referring to the drawings by, numerals, the apparatus of myinvention comprises an elongated, narrow, open top tank I of rectangular0 form constructed of molded glass, or similar transparentmaterial, andincluding a flat bottom 2, ends 3 and front and rear 'sidesl and 5.Extending transverselyibetween the sides 4' and5 and preferably moldedtherewith are laterally spaced parallel bars 6 of glass which may beeither 1 gcylindrical or otherwise formed as desired. The fijbars- 6.are arranged'and designed so that the opposite ends thereof at the frontand rear sides 4' and 5 formdarkened. preferably duplicate dejsigns atsaid frontand rear sides readily visible through the latter. letterdesign designated 1, has been shown for f the purpose of illustration. 1

Covering the rear side 5 ofthe tank I is a dished reflector 8 ofsuitable material, for instance, cardboard, having its open side opposedto 'saidside 5. The reflector 8 is de'tachably secured to the top edgeof the side 5 by means of hooks 9 ffafiixed to said reflector as at Illand taking over said edge. In the longitudinal center of the rcflector8, a plurality, two being shown,of electric f [light bulbs II aremounted, in the back of said j T 1 reflector, to be connected in theusual manner to thie house circuit as by means of cable connec,

tions, represented at I2.

In the present instance, a

"I'he front side [of the tank I has formed therein, adjacent the bottom2, a conduit I3 extending from one end through to the other and openingonto one end of the tank. Branching laterally from the conduit I3 andopening into the interior of the tank I is a plurality of ports I4equi-distantly spaced apart along said conduit. The open end of theconduit I3 is socketed as at l5 for the attachment of an airline I5 tothe tank I in communication with the conduit. The airline I 6 isdesigned to admit air under pressure, from a suitable source, not shown,into the conduit l3 and a suitable valve I I is interposed in said lineto regulate the flow of air therethrough.

In the use of the invention, the tank I is filled with any suitableliquid, of any desired color, and air is admitted to the conduit I3 byopening of the valve H, such air aerating the liquid in the tank by wayof the ports I4 thereby forming bubbles and creating a colored sparklingbackground for the design I, the light bulbs II illuminating the designby way of the bars 6 in a manner which will be clear.

In connection with the use of the apparatus it may be explained, that myinvention comprehends making the bars 6 of different colors, utilizingdifferently colored light bulbs, and coloring the reflector 8, so thatby substituting differently colored light bulbs I I in the reflector 8 awide variety of color combinations may be produced for illuminating thedesign or display.

' For instance, when using a full set of variously colored glass bars 6and red light bulbs I I, yellow bars will show as orange in the designand light blue bars will show violet. If amber light bulbs II are used,red bars will show dark orange, dark blue bars gray and violet coloredbars will show a maroon color. If blue light bulbs are used, red barswill show violet and yellow bars show green and orange bars show asbrown. By using a green light bulb I I white bars show as green andorange bars as yellow.

If desired the bars 6 may be coated with silver nitrate which improvesthe reflection of the light rays therethrough'.

. My invention will, it is believed, be readily understood from theforegoing without further explanation.

,Manifestly, the invention as described, is susceptible of modificationwithout departing from the inventive concept and right is hereinreserved to such modifications as fall within the scope of the subjoinedclaims.

What I claim. is: a

1. Advertising apparatus comprising a tank or rectangular form andtransparent material and including front and rear sides, a plurality ofspaced apart transparent bars extending between said sides and formingat the juncture therewith designs visible through said'sides, and meanson the rear side of the tank for illuminating said rear side.

2. Advertising apparatus comprising a tank of rectangular form andtransparent material and including front, and, rear sides, a v pluralityof spaced apart transparent bars extending between said sides andforming at the juncture therewith designs visible through said sides, areflector on,

sides, means on the rear side of the tank for illuminating said side,and means to introduce air under pressure into said tank at spaced apartpoints along the lower part of the tank.

4. Advertising apparatus comprising a liquid containing tank ofrectangular form and transparent material and including front and rearsides, a plurality of spaced apart transparent bars extending betweensaid sides and forming at their juncture therewith designs visiblethrough said sides, means on the rear side of the tank for illuminatingsaid side, and means to introduce air under pressure into said tank atspaced apart points along the lower part of the tank and including aconduit in one side of the tank extendinghorizontally along said sideand open at one end, said side of the tank having ports therein 1 spacedalong said conduit and establishing com-
